IMO SI25A 800V Enclosed DC Isolator Switch for PV Installs

#2:  IMO-SI25-PEL64R-4 Switches - DC Isolators

Reliable DC Isolator for Photovoltaic Installations

The IMO SI25 Enclosed DC Switch Disconnector is a robust and safety-focused isolator designed to protect solar PV systems. Built to meet IEC 60364-7-712 compliance, this isolator ensures secure disconnection between the DC/AC inverter and the solar panel array, making it essential for all photovoltaic installations.

With 4 poles (2 strings), an IP66-rated enclosure, and IMO’s patented Safelock function, it delivers maximum safety, fast switching, and long-term durability in harsh environments.
